Fragrance Oils or Essential Oils – What’s Best for Your Candle?

Fragrance Oils vs. Essential Oils: Which One Belongs in Your Candle?

When making scented candles, you typically have to choose between fragrance oils and essential oils. Both create beautiful aromas, but they differ significantly in origin, strength, safety, and price. Let's explore their unique qualities to help you decide which is best for your candle-making needs.

What are essential oils and fragrance oils?

Essential oils come from plant material. Producers extract them through methods such as steam distillation or cold pressing to capture the plant’s pure essence. Manufacturers create fragrance oils by blending synthetic or natural aroma compounds with a neutral carrier oil. These compounds are lightweight and quickly reach your scent receptors.

Key Differences Between the Two

1. How They’re Made:
   Essential oils rely on raw plant material, such as flowers, roots, or leaves. Fragrance oils don’t require real plants. Labs formulate them with natural or chemical ingredients. This difference affects the complexity, purity, and sustainability of the scent.
2. Scent Strength:
   Fragrance oils tend to deliver stronger scents. A single drop can fill a room more intensely than an equal amount of essential oil. This is because manufacturers design fragrance oils for scent impact, whereas essential oils retain a more subtle, natural aroma.
3. Oil Usage in Candles
   You often need more essential oil to match the scent strength of fragrance oil in a candle. Essential oils are pure and undiluted, which makes them potent but also means you’ll use more of them per candle to reach a comparable intensity.
4. Shelf Life
   Both oils have a long shelf life when used in candles, but it varies based on storage, ingredients, and environmental factors.
5. Safety Considerations:
   Both oil types are generally safe for use in candles. However, always follow the manufacturer's guidelines. Some essential oils may irritate the skin or cause allergic reactions. Just because something is natural doesn't mean it's harmless.
6. Price Differences
   Since essential oils are derived from plants and require extensive processing, they tend to be more expensive. Since candles made with essential oils require a higher volume of oil, their production cost also rises. However, many people find that the wellness benefits of aromatherapy are worth the extra investment.
